You have definitely made some great progress !!!
The Corsair is my favorite all time plane and this one is looking good …….. The Corsair looks best with the flaps dropped like you are doing.
Are you going to fill in the step on the starboard side inboard flap or leave it be ???
My understanding is that the early F4U’s had this step area covered with a small spring loaded door. Later in the production run (around the Dash 1D planes ) is when they started to use the open step on planes.
But keep in mind, these parts were occasionally replaced in the field with the newer style flap. So it can be possible the flap was open like you have here.
Looks great my friend !!!
Now I want to build a FAA Corsair for the 100 Years of the RAF.
